STORA ENSO_FINLAND: WOOD-BASED BATTERY CAN TRIPLE CHARGING SPEED OF CAR BATTERIES

The battery cluster planned in Finland will acquire its first industrial-scale facility with Stora Enso’s anode material factory to be built in the near future. Battery production will move into the bio-economy era, as most of the anode material needed for rechargeable batteries can soon be manufactured from a wood-based raw material.
In producing anode material for batteries, Stora Enso is entering a completely new business. In principle, however, the production will not increase the use of wood to a great extent, since the material is made from by-products of the wood pulping process.

In practice, the relative value of what is produced may change radically. What has been the principal product so far, in other words, cellulose fiber, may end up being a by-product.
During the Capital Markets Day event organized for investors by Stora Enso last autumn it was stated that the company is expecting a turnover of thousands of millions with the battery material business. Judging by the price of the end products and the production volumes envisaged, this may well be possible. Even a rough comparison shows great promise: using the current average price per metric ton of USD 1,000, considered relatively high, it is estimated that the gain per kilo of the anode material would be 15–200-fold.
The quantities can also be substantial. It is estimated that in 2030, the annual demand for anode materials will be about a million tons in Europe and about four million tons globally. Stora Enso estimates that in 2030, it will be able to produce 80,000–100,000 tons of anode material in two factories.
Does this mean that the pulp from a pulp mill could actually become a by-product?
’Well, I can only be pleased if Sunila has two legs to stand on, instead of just one,’ says Timo Tidenberg, Director of the Sunila Mill.
